The invention discloses a data quality discrimination method for roadside traffic signal lamp data acquisition equipment. The method comprises the following steps: S1, installing the roadside traffic signal lamp data acquisition equipment at an intersection controlled by signal lamps; s2, the roadside traffic signal lamp data acquisition equipment processes the acquired signal lamp data into structured data and stores the structured data; s3, based on the stored signal lamp data, comprehensively judging data quality from five dimensions of data existence, uniqueness, integrity, accuracy and timeliness; and S4, completing the judgment of the five dimensions, ending the whole data quality judgment process, and storing and backing up the judgment calculation result. Through the above design, the data quality is comprehensively judged from five dimensions of data existence, uniqueness, integrity, accuracy and timeliness, and the data uploaded by the roadside traffic signal lamp data acquisition equipment can be subjected to quality standard judgment, so that the availability and reliability of the signal lamp data are improved.

    本发明公开了一种路侧交通信号灯数据采集设备的数据质量判别方法,包括步骤S1、在有信号灯控制的交叉口安装路侧交通信号灯数据采集设备;步骤S2、路侧交通信号灯数据采集设备将采集的信号灯数据处理成结构化数据并存储;步骤S3、基于上述存储的信号灯数据,从数据存在性、唯一性、完整性、准确性和时效性5个维度综合判断数据质量;步骤S4、以上5个维度判别完成,结束整个数据质量判别流程,将判别的计算结果进行存储和备份。通过上述设计,本申请从数据存在性、唯一性、完整性、准确性和时效性5个维度综合判断数据质量,能够对路侧交通信号灯数据采集设备上传的数据进行质量达标判别,进而提高信号灯数据的可用性和可靠性。
